description The invention relates to a reinforced concrete flexural member bearing capacity time-varying probability modeling method based on an MC method, and belongs to the field of structural reliability analysis, and the method comprises the following steps: taking the thickness c of a concrete protective layer and the compressive strength fc of concrete as random processes changing along with time; based on the Monte Carlo principle, generating a certain number of samples according to a known probability model; according to a corresponding calculation model, taking the carbonization residue x0 and the corrosion depth delta cr of the steel bar during cracking as a function of c, taking the corrosion speed lambda e1 of the steel bar before the cracking of the concrete protection layer as a function of c and fc, and taking the functions as random processes x0 (t), lambda e1 (t) and delta cr (t); and by parity of reasoning, correcting the statistical characteristic value of the random process of the unknown probability
